Chronic wasting disease: change in documented distribution in North America 2000-2024

The Strain and Genetic Online Tissue Repository (SAGOTR) is being developed by the USGS Fort Collins Science Center to document, track, discover, and request physical samples of Chronic Wasting Disease (CWD). SAGOTR connects natural resource managers, tissue repositories, and researchers in one online platform, making it easier to locate and share samples and support research and management of CWD...

Chronic wasting disease (CWD) has been detected in 36 US states and five Canadian provinces in free-ranging cervids and/or captive cervid facilities.

To support management decisions concerning 500 bison and 8,000 elk in Jackson, Wyoming, USGS scientists assessed how alternative U.S. Fish and Wildlife Service plans for providing supplemental food would influence: 1) chronic wasting disease prevalence, 2) elk and bison numbers, 3) wildlife movement and human-wildlife conflict 4) multiple use opportunities for the public, like hunting, and 5)...

Chronic wasting disease (CWD) is an emerging infectious disease that is fatal to free-ranging and captive animals in Cervidae, the deer family. CWD is one member of a family of diseases called transmissible spongiform encephalopathies (TSEs), and is thought to be caused by prions. CWD is the only TSE known to affect free-ranging wildlife.
